A samurai wouldn't be ideal, as the class is a mounted warrior-type and a lot of the next game will be a dungeon crawl in a wizard academy (can you see the theme?).

Psions are considered exotic to Nora, but not unknown. The biggest decision you'd have to consider is whether you were a member of the Pyramid or not. They Pyramid is an organization bent on controlling psionics throughout Nora and through them, the aristocracy itself. They are a LN/LE organization and are widespread.

You do not have to be a member of this secret organization, but by deciding such, you become a person of interest to them and they would hunt you down if they knew of you.
